    Zip up in midweight merino.

    Named after New Hampshire's Mount Isolation, the Minus 33 Men's Isolation Midweight Zip-Neck Top is built to keep you warm and dry when you make a summit push in the high mountains. This midweight merino wool shirt is ideal for cold-weather hiking and alpine touring, and the natural antimicrobial properties of the merino wool are nice both for you and your hiking or touring buddies. With its 1/4-zip top, you can get some extra ventilation when you need it.

    I'm a fan

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: XXL
    • Height: 6'4"
    • Weight: 250lbs

    Minus 33 was an unknown brand to me but I decided to give it a shot as the price was attractive. I'm a fan now. I've bought both the mid and expedition weight zip t-necks and like them both a lot. Very well constructed and durable. Warm and attractive without any frills. I have 37" sleeves so bought the XXL to accommodate. I did find that the pieces run a bit small so was glad for the extra sizing. Good stuff at a good price!

    When it's working

    • Fit: True to size

    The Zip-Neck is working; that is keeping you warm, only after you've actually generated some body heat. Then it is really great since it is so light. Do not expect this warmth if you aren't wearing a windbreaker on a cold windy day.

    Like the zip neck! Really I use this more as an everyday pull on over a T-Shirt for a cool day. Use it skiing - BC and lift access; any winter activity really. Personally - climbing, skiing, running, backpacking I have used it on all of these and always loved having it!
